Associations of elevated weight status with symptom severity and treatment outcomes in binge/purge eating disorders

Abstract
Objective: Binge-eating and purging behaviors commonly co-occur with overweight. However, little is known about the potential associations of elevated weight status with eating disorder severity or treatment outcomes. Thus, the present study compared binge-eating and purging patients with low, normal, and high weight statuses on eating disorder and mood symptoms at treatment admission, and tested whether weight status was associated with symptom change over treatment.
Method: The sample included 135 adult female patients in an intensive outpatient program, who completed self-assessments at admission and discharge. MANOVAs compared the groups at treatment admission, and multilevel models examined changes over time.
Results: At admission, the high-weight group reported greater fasting frequency than the normal-weight group, and higher shape and weight concerns than the low-weight group. Over time, the high-weight group additionally showed higher eating disorder psychological symptom severity than the normal-weight group. The groups did not differ on mood symptoms at admission. Longitudinal results indicated that the groups showed comparable symptom improvements over treatment.
Discussion: These findings highlight the severity of higher-weight patients with bulimia nervosa. Additionally, although these patients may present with more severe symptoms, their response to an intensive treatment may be comparable to that of normal- or lower-weight groups.
Keywords: binge eating; bulimia nervosa; eating disorders; overweight; purging; treatment outcome.
